The kids' school hosted its annual Harvest Festival this past weekend. One of my favorite crafts was a repeat from last year, but they did it one better: In the previous incarnation the kids hammered flowers onto scraps of cloth and it wasn't really clear what you would do with it. This year the organizers gave the kids plain white scarves to decorate.
Very simply, they had the children pick out colorful flowers which were then laid out on half the cloth. The fabric was then folded in half and the kids handed a hammer to thwack the dyes in to the scarves. The result is lovely, eh? To set the dyes, all you need to do is toss your finished piece in the dryer. Easy peasy.
